We want to clarify to everyone that, there was a misunderstanding about two different version of Dhanvantari mantra:
We just would like to say that the following is the mantra - is the correct version that we request devotees to chant:
oṁ namo bhagavate
vāsudevāya dhanvantaraye
amṛta-kalaśa hastāya,
sarvāmaya vināśanāya,
trailokya nāthāya
śrī mahāviṣṇave namaḥ
From Jayapataka Swami Maharaj
